Friction and Force Basics

Front

What is friction?

Back

Friction is the force that opposes the relative motion of two surfaces in contact.

Front

How does friction affect the motion of an object?

Back

Friction can slow down or stop the motion of an object depending on the surfaces in contact.

Front

What happens to an object's speed when there is more friction?

Back

More friction decreases the speed of the object.

Front

What is the relationship between surface roughness and friction?

Back

Rougher surfaces have greater friction compared to smoother surfaces.

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size but opposite in direction, resulting in no change in motion.

Front

What effect do balanced forces have on an object's speed?

Back

Balanced forces do not change the object's speed.

Front

What is the direction of the frictional force relative to motion?

Back

The frictional force acts in the opposite direction of the motion.

Front

What is static friction?

Back

Static friction is the frictional force that prevents two surfaces from sliding past each other.

Front

What is kinetic friction?

Back

Kinetic friction is the frictional force acting between moving surfaces.

Front

How can friction be reduced?

Back

Friction can be reduced by using lubricants, smoothing surfaces, or using wheels.
